HEATING APPARATUS.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed April 18,1906. Serial No. 312,396.

To all whom it may concern.-

Be it known that I, FRANK A. DELPH, a citizen of the United States,residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented new and useful Improvements in HeatingApparatus, of which the following is a specification.

My invention pertains to heating drums; and it has for its object toprovide a heating drum apparatus designed to be used in conjunction withan open fire, and embodying such a construction that perfect combustionof the fuel is assured, and all of the heat values are diverted into anapartment and utilized to heat the same instead of being permitted toescape up the chimney.

Other practical advantages peculiar to my invention will be fullyunderstood from the following description and claims when the same areread in connection with the accom planying drawings, forming part ofthis specication, in which: k

Figure 1 is a vertical section illustrating the apparatus constitutingthe present and preferred embodiment of my invention as properlyarranged relative to an ordinary open fire-place; one of the heatingdrums being shown partly in side elevation and partly in section. Figs.2 and 3 are sections taken in the planes indicated by the lines 22 and3-3, respectively, of Fig. 1.

Similar letters designate corresponding parts in all ofthe views ofthedrawings, referring to which:

A is an open fire-place having an ordinary or any other suitable basketgrate a and a flue or chimney 1). Before my novel apparatus is placed inits working position, the course of the products of combustion from thefire in the grate a is directly up the flue or chimney b, and after theapparatus is arranged as shown in Fig. 1, relative to the fireplace, thecourse of the products of combustion is always through the heating drumsof the apparatus.

B is the portable apparatus constituting the present and preferredembodiment of my invention. The said apparatus comprises one or more,preferably two, heating drums C, a frame D carrying the said drums andprovided with anti-friction rollers E for facilitating the removal ofthe apparatus from one apartment to another as well as movement of theapparatus toward and from the fire-place, a plate F fixed with respectto the inner portions of the drums O and designed to close the portionof the fire-place above the grate a, a horizontal partition G carried bythe plate F and having for its ofiice to prevent direct passage of theproducts of combustion from the grate to the flue b and to compel suchproducts to take passage through the drums O, and a foraminated cover H,preferably of reticulated material as shown, surrounding the drums C andconnected to the frame D and plate F, and designed to add stiffness andstrength to the apparatus and to prevent persons coming in contact withthe drums O as well as to serve as a plate and food warmer and a drierfor clothes and other articles.

As best shown in Fig. 2, the drums O are arranged in parallel verticalplanes, and each comprises a lower stretch c which is preferably, thoughnot essentially, oval in crosssection so as to assure a largepipe-heating surface in proportion to the size or area of the plate F,an upper stretch d preferably of the same shape in cross-section as thestretch a, and an elbow e connecting the outer ends of the stretches cand d and containing a damper f for controlling the passage of productsof combustion through the drum. The dampers f of the two drums arepreferably fixed on a common shaft g, Fig. 2, and the elbows e arepreferably removable from their respective stretches c and d, thislatter to facilitate cleaning of the drums when the same is necessary.

As best shown in Fig. 1, the plate F is provided on its lower portionwith a flange F designed to complete the cut-off and support the innerend of the apparatus on the grate a.

It is obvious that in practice the anti-friction rollers E of frameDmaybe made adjustable vertically with respect to the said frame fordifierent levels; also, that by making the plate F large enough to coverthe upper portion of thelargest fire-place and equipping it with anadjustable section, the apparatus may be used in combination withdifferent fire-places in different apartments if desired.

In the practical operation of my inprovements it will be apparent thatthe products of combustion from the fire in the grate a are caused bythe partition G on plate F to pass through the drums O precedent topassing up the flue or chimney b, and consequently the heat of saidproducts is radiated from the drums and used to the best advantage inheating the apartment containing the apparatus.

\Vhen it is necessary to supply the fire in the grate a with fuel, it isobvious that the same may be conveniently accomplished after my novelapparatus is moved away from the fire-place.

It will be gathered from the foregoing that my novel apparatus is lightin weight and readily portable; also, that when the apparatus isemployed the combustion in the grate is complete, it is not necessary todisturb the fire in order to keep the same active, and the fuel iscompletely reduced to ashes Without the loss of particles which rendersit feasible to employ a grate having very small openings and in that wayreduce waste to a minimum.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a definite understandingof the said embodiment. I do not desire, however, to be understood asconfining myself to the said specific construction and relativearrangement of parts as such changes or modifications may be made inpractice as fairly fall within the scope of my claimed invention. Havingdescribed my invention, what I claim and desire to secure byLetters-Patent, 1s:

A portable heating drum apparatus comprising a supporting frame, a platecarrying a horizontal partition, and one or more heating drums orconduits carried by the frame and plate and having lower and upperstretches open at their inner ends and communicating with the spacesabove and below the horizontal partition and connected together at theirouter ends and a foraminated or open-work cover surrounding the drum ordrums and connected to the frame and the plate.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

FRANK A. DELPH.
